HACK HACK HACKETY HACK: Since Chrome won't give us a file path, we have to
|
|
find our own ways to identify unique files (so that we don't re-open them).
|
|
In order to do that, we'll try to get the unique information about a file,
|
|
and return it as a concatenated string that the sessions module can use to
|
|
check against a new file. This should work in the short term, but it could
|
|
be fooled by any files that are different, but A) named the same, B) the
|
|
same size, and C) dated the same. Rare, but possible.
|
|
|
|
Oh, and for added suck, it's async.
